I am using delete in the general sense ie fclose, closedir, etc. And
even though this doesn't directly map here, this also holds true for
resources that been obtained with allocators; it is not perfectly
fine to deallocate them if they are null(20.1.5) even though I would
assert that a handle to resources obtained with
std::allocator::allocate conform to a pointer concept.
